Answer:

a. Bisector is at point M

b. [tex]AB = 98[/tex]

Step-by-step explanation:

Question is not well formatted:

Given

[tex]AM = 4x+1[/tex]

[tex]MB = 7x-35[/tex]

Solving (a): The segment bisector

From the given parameters above

We have AM and MB

The common point in AM and MB is M;

This indicates that the bisector is at point M

Solving (b): The value of AB

First we need to determine the value of x

Because M is the point of bisector;

[tex]AM = MB[/tex]

[tex]4x + 1 = 7x - 35[/tex]

[tex]4x - 7x = -1 -35[/tex]

[tex]-3x = -36[/tex]

Solve for x

[tex]x = -36/-3[/tex]

[tex]x =12[/tex]

Next is to determine the value of AB using

[tex]AB = AM + MB[/tex]

[tex]AB = 4x + 1 + 7x - 35[/tex]

Collect Like Terms

[tex]AB = 4x + 7x + 1 - 35[/tex]

[tex]AB = 11x - 34[/tex]

Substitute 12 for x

[tex]AB = 11 * 12 - 34[/tex]

[tex]AB = 132- 34[/tex]

[tex]AB = 98[/tex]
